Katy B and Neon Jungle are the latest additions to this year's UK Live lineup.
The 'Crying For No Reason' hitmaker - whose album 'Little Red' recently topped the UK album chart - is among the latest names to sign up for the British music festival, taking place in June.
'Braveheart' hitmakers Neon Jungle will also perform at the trio of concerts - taking place in Ipswich, Sunderland and Weston-super-Mare - as will pop newcomers Rixton.
Katy B commented: "I'm looking forward to playing such huge outdoor shows. This will definitely be a summer highlight for me."
Neon Jungle added: "We're so excited to play this festival as we get to perform on the same stage as some of our favourite artists!"
UK Live will kick off with North East Live at the Sunderland Stadium of Light on June 22. The pop fun then moves to Ipswich Chantry Park on June 28 for East Coast Live, and then to Weston-super-Mare Beach on June 29 for South West Live.
The festival will be headlined by 'Wild' singer Jessie J and other performers include chart-topping girl band The Saturdays, The Vamps, Union J, Rizzle Kicks and US star Jason Derulo, playing his only live outdoor UK dates of 2014.
